Ultra-light, extra-ventilated, high-performance running socks for maximum thermoregulation and sweat wicking in hot conditions.
When things start to heat up on the road, it's best to have a good pair of socks on your feet. And you won't go wrong with the brand-new generation of PRS Ultralight Run, designed for optimum thermoregulation during training and racing in hot conditions. The lightweight, technical mesh is designed to fit like a second skin. It offers exceptional ventilation and rapidly wicks away perspiration to keep your feet cool and dry, even in tropical climates. The revised and enlarged "toe reinforcement" toe zone offers an ergonomic fit and improved proprioception, allowing the toes to expand intuitively on landing for a natural, fluid stride. A special mesh around the ankle, lighter than the classic Compressport running sock, offers gentle support as you push the pace. Characteristic arch support prevents the fabric from twisting and chafing in the heat, while a terry cloth reinforcement around the big toe keeps your nails from getting blackened over the miles. Say goodbye to blisters! The signature 3D.dots and new Flat.dots on this ultra-lightweight model save volume and weight while delivering high performance. All along the Achilles tendon, they offer additional protective support and ventilation during fast runs. Underfoot, an intelligent pattern comprising 50% 3D.dots and 50% Mesh.dots cushions impact and adds grip in the shoe. It also provides gentle micro-stimulation to increase venous return, and improves ventilation by increasing air flow between points. The sock height is lower than that of the trail and bike models to meet the demands of road racing. An ergonomic tongue at the back adds a touch of comfort and style, and if you forget why you're going out, the discipline is discreetly embroidered on the inside.
An explosive blend of technology in a lightweight package, this 4th generation Ultralight running sock is your new weapon of choice for tackling the Sahara desert or a Boston heat wave.
